Information × Registration Number 0201U001937, 0197U016347 , R & D reports Title Development of the method for growing and putting into production crystals for elements of passive optics used in lasers of the IR region and active elements for lasers with diode pumping popup.stage_title Head Kosmyna Miron Bogdanovych, Registration Date 26-02-2001 Organization Department of Optical and Constructional Crystals of STC <Institute for Single Crystals> popup.description2 In the process of conduction of scientific research works the equipment for growing large sapphire and yttrium orthovanadate crystals have been modernized. The methods for the preparation of raw material from alumina of the mark Г-00 for growing sapphire and raw powder for growing yttrium orthovanadate crystals have been developed. The method for growing large (250x250x30 mm) sapphire crystals of high optical quality has been put into experimental production. The technological yield of commercial crystals has been increased from 60% to 80%; their weight has changed from 4 to 6 kg. The experimental samples of sapphire products - optical windows to 200 mm in diameter have been prepared; yttrium orthovanadate crystals (YVO4:Nd) O25x50 mm and active laser elements on their basis diam. 2-5 mm and to 50 mm long have been grown. Application field: laser engineering. Product Description popup.authors popup.nrat_date 2020-04-02 Close
